Coal Stockpile Design

Plant Design: Trends in Coal Pile Design

The key elements of the final design were a longitudinal stockpile and a rail-mounted, bucket-wheel machine (Figure 4) that can stack coal at 1,500 tph and reclaim it at 2,200 tph.

coal stockpile design -

Coal Stockpile Design. Gravity reclaim stockpiles are used for the shortterm storage of bulk materials during material handling processes. The design of associated storage and handling facilities requires knowledge of the bulk solid material characteristics over a range of different operating conditions.

Coal Pile Management | Coal Stockpile | RPM Solutions ...

A coal stockpile is a pile or storage location for bulk materials. More controlled stockpiles are used in many different areas and are formed using stackers to form piles along the length of a conveyor and reclaimers to retrieve coal when required for product loading.

Inactive Coal Stockpile Design Considerations

Jul 07, 2007 · Inactive Coal Stockpile Design Considerations At the moment my company is considering options to cover the inactive coal stockpile to minimise the potential for coal fires. There seems to be a couple of options including covering the pile with a tarpaulin (plastic covering), spraying on a stone or compacting it.

Optimised coal handling - ABB Group

From the mine to the plant. Coal handling systems are an integral part of a complete material flow and quality management system (Figure 1). In recent years, the main focus was on the optimisation of single parts of this system, such as mine planning or advanced automation solutions.

Effect of aggregate stockpile configuration and layout on ...

In practice, many stockpiles are stored and loaded by forcing machine with special arrangement space in a real storage yard. In a general manner, coal is stocked via a combined stacker reclaimer which runs parallel to the piles along the centre rail track. Wheel loaders and mobile hoppers are used to load coal into trucks or trains.

Mine stockpile design to minimise environmental impact

Mine stockpile design to minimise environmental impact J. E. Everett Faculty of Economics and Commerce, The University of Western Australia Abstract In Western Australia, iron ore is extracted from inland mines and railed to a port, where it is loaded onto ships for export. Quality depends upon uniform

Stockpile Volumes - Engineering ToolBox

Anthracite coal with density 65 lb/ft 3 is stockpiled in a conical pile with diameter 30 ft and height 8 ft. According the diagram above the volume of the pile is approximately 2000 ft 3. The total mass of the pile can be calculated as w = (65 lb/ft 3) (2000 ft 3)

Guidelines MDG 28: Safety requirements for coal stockpiles ...

When the stockpile dozer has a full blade of coal, the volume of coal may fill the draw down hole and reduce the risk. If there is little or no coal in front of the blade, the risk of the dozer going down into the draw down void increases. The dimensions of the dozer and the stockpile height influence the risk.

Jan 2013 1 of 3 Safety Modifications for Coal Storage Pile ...

Active Stockpile Any coal stockpile that feeds into underlying feeder systems with the potential for pile cavity formation, regardless of the pile dimensions or the proximity of the pile edges to the feeder(s).

Soil Stockpiling for Reclamation and Restoration ...

Soil Stockpiling for Reclamation and Restoration activities after Mining and Construction . Patti Strohmayer . Stockpiling is a necessary part of civil engineering and mining operations. Stockpiling involves removing the topsoil (the A and B horizon of the soil). The topsoil is usually removed with

Management of coal stockpiles, CCC/23 | IEA Clean Coal Centre

Stockpile management is an important part of the coal handling process from mine to customer. Virtually all coal producers and consumers make use of stockpiles at their facilities, either to serve as a buffer between material delivery and processing, acting as a strategic stock against supply interruptions; or to enable coal blending to meet quality...

Improving fundamental stockpile management procedures

Coal being reclaimed from stockpile must meet pre-defined quality specifications. The optimisation model automatically determines a reclamation schedule to meet these specifications in the most economic fashion based on the value and quality of available coals.


The coal stockpile in most of the power plants will be formed by the rail mounted, slewing and luffing type stacker. The stockpile formed by this will be either triangular shape or trapezoidal shape.

Coal preparation plant - Wikipedia

A simple stockpile is formed by machinery dumping coal into a pile, either from dump trucks, pushed into heaps with bulldozers or from conveyor booms. More controlled stockpiles are formed using stackers to form piles along the length of a conveyor, and reclaimers to retrieve the coal when required for product loading, etc. Taller and wider stockpiles reduce the land area required to store a set tonnage of coal.

Coal Stockpile Height -

Jun 02, 2015 · I am working on a project in Indonesia for a coal export terminal. The volatile material content in coal is 39 %. I read somewhere that this is considered as high volatile and the stockpile height should be restricted to 4 m. In that case I will have to have very long stockpile. I have designed the system with 15 m heigh pile. Open to forum for guiding on best solution.

The Optimal Layout Design for Coal Stockpiles

The various aspects involved in selecting a suitable layout of the stockpile for coal storage and coal terminals are discussed. Average throughput and peak capacity, blending/homogenization ...
